Cord-blood 25-hydroxyvitamin D levels and risk of early-onset neonatal sepsis: a case-control study from a tertiary care center in Turkey.

UNLABELLED: Vitamin D has been linked with immunity, and the immunomodulatory role of this molecule in regulating key elements of the immune system has become an area of intense scientific investigation. We designed a case-control study to investigate whether neonates with early-onset neonatal sepsis (EONS) had lower levels of vitamin D. The primary exposure for the analysis in the study was the cord-blood level of 25-hydroxyvitamin D (25(OH)D). Of the 2571 live births occurring during the 18-month study period, 53 infants were admitted to the neonatal intensive care unit with suspected EONS. After clinical and laboratory confirmation, 40 newborns with EONS and 43 controls were analyzed. Cord-blood 25(OH)D levels of infants in the study group were significantly lower than that of the control group (median 12.6 ng/mL (3.1-78.9) vs. 21 (5-118); p = 0.038, respectively). In multivariate models, a low cord-blood 25(OH)D level (<30 ng/ml) was associated with an increased risk of EONS (OR = 5.6; 95% CI = 1.3-23.5). CONCLUSION: Cord-blood 25(OH)D levels of neonates with EONS were significantly lower than that of the healthy controls, and a low level of cord-blood vitamin D was found to be associated with an increased risk of EONS. Further studies are warranted to confirm this association.

Bohn's nodules: peculiar neonatal intraoral lesions mistaken for natal teeth.

Inclusion cysts of transient nature during the neonatal period are developmental lesions, which are seen in the oral cavity of the newborn infant. These lesions are classified into three subtypes according to their localizations. When noticed by the anxious parents on the gingival surfaces, they are often mistaken for natal teeth, which lead to seeking medical attention. Herein, we describe a newborn infant with Bohn's nodules to increase the awareness of the physicians to this benign, self-limiting lesion.

Factors influencing breastfeeding duration: a survey in a Turkish population.

UNLABELLED: Breastfeeding provides perfect nutrition for infants and is a source of many health benefits for both mother and baby. To obtain the maximum beneficial effects of breast milk, it is necessary to prolong the breastfeeding duration. In this study, we investigated the factors influencing the duration of breastfeeding. We conducted a 32-question survey of mothers with children aged 2-4 years, who presented to our medical school's pediatric outpatient clinics. The questionnaire solicited information on demographics and breastfeeding attitudes. We found correlations between total duration of breastfeeding and the time the mother and baby spent together (sharing a room to sleep at night) and the father's engagement in breastfeeding. Breastfeeding duration inversely correlated with maternal employment. Total duration of breastfeeding did not correlate with breastfeeding education by health personnel, the mother's education level, the gender of the child, regular prenatal care visits, the use of a pacifier, the interval between birth and the onset of breastfeeding, gestational age, method of delivery, or the birth weight of the infant. CONCLUSION: Our findings suggest several strategies to increase the duration of breastfeeding, including educating fathers along with mothers, supporting a shared bedroom until the child is 2 years of age, and promoting measures that allow mothers to be with their children during working hours.

Neonatal tooth in a preterm infant.

A neonatal tooth is defined as a tooth, which erupts within the first month of life. Herein, we report a premature infant with a neonatal tooth.

Do not overlook an umbilical cord hernia before clamping.

An umbilical cord hernia is a rare midline abdominal defect. These masses may be easily overlooked at birth, which may result in an intestinal injury due to careless proximal application of the cord clamp. Herein, we present a newborn infant with an umbilical cord hernia who was managed by primary closure of the lesion.

Cerebral sinovenous thrombosis associated with MTHFR A1298C mutation in the newborn: a case report.

Although cerebral sinovenous thrombosis (CSVT) is a rare condition in the neonatal period, high rates of morbidity and mortality necessitate the establishment of an early diagnosis. Methylenetetrahydrofolate reductase (MTHFR) plays a central role in the folate cycle and mutations of MTHFR are associated with vascular disease. While the C677T common missense mutation is the most well-defined MTHFR polymorphism, another common missense mutation, A1298C also exists. There has been no reported case of CSVT associated with MTHFR A1298C mutation in the neonatal period. Herein, we report a neonate with CSVT who was found to have MTHFR A1298C homozygosity.

Social prejudice hindering proper use of car safety seats.

The compliance of parents with child passenger safety (CPS) has been mainly explained by their level of knowledge. Social, ethnic and cultural factors have not been investigated in detail. This study investigated the rate of compliance of parents with CPS guidelines, as well as the factors hindering it. Parents of infants aged 2-10 days were enrolled. The proportions of families obtaining a car safety seat (CSS; 57%) and complying with CPS recommendations (2%) were very low. Most of the parents thought CSS were harmful for infants (mother, 57%; father, 63%), despite having already purchased one. Parents believed their children to be too small to use CSS and cannot sit in CSS because they should lie flat on their backs at all times. These prejudices may be due to the social and cultural circumstances specific to Turkey, or corresponding findings may be found in countries with similar socioeconomic status.

Red cell distribution width (RDW) in the newborn: normative data.

AIM: To evaluate the normal range of red blood cell distribution width (RDW) in term and preterm newborns dependent on gestational age. MATERIAL AND METHODS: A total of 1,594 preterm and term neonates were admitted to our neonatology department. Infants were divided into two groups according to their gestational age. Group 1 consisted of infants with ≤34 weeks of gestation; group 2 consisted of infants with ≥35 weeks of gestation. Infants in Groups I and II were subdivided according to their gestational age. Gestational age, birth weight, sex, hemoglobin and hematocrit, MCV levels of all newborns were recorded, and RDW was compared between the groups. RESULTS: A total of 1,594 newbornswere enrolled in the study. Group 1 (≤34 weeks) consisted of 725 newborns and Group 2 (≥35 weeks) consisted of 869 newborns. The mean normal range of RDW in Group 1 was 17.8 ± 2.1 and of group II was 16.7 ± 1.6 (P<0.05). The normal range for RDW values at 32-34 weeks was higher than at 35-36 gestational weeks, and at 37-42 weeks (P = 0.002 and 0.003). CONCLUSION: RDW values at ≤34 weeks in newborns are higher than at ≥35 weeks. This may be useful in the differential diagnosis of neonatal hematologic diseases together with other red cell parameters.

Protective effects of caffeic acid phenethyl ester (CAPE) on intestinal damage in necrotizing enterocolitis.

OBJECTIVE: To determine the preventative effect of caffeic acid phenethyl ester (CAPE) in necrotizing enterocolitis (NEC) in an experimental rat model of NEC. MATERIALS AND METHODS: Thirty newborn Sprague-Dawley rats were randomly divided into three groups; as NEC, NEC + CAPE and control. NEC was induced by enteral formula feeding, subjected to hypoxia-hyperoxia and cold stress. Pups in the NEC + CAPE group were treated with CAPE at a dose of 30 mg/kg daily by intraperitoneal route from the first day to the end of the study. All pups were executed on the fourth day. Proximal colon and ileum were allocated for histopathologic and biochemical evaluation, including xanthine oxidase (XO), total antioxidant status (TAS), total oxidant status (TOS), malonaldehyde (MDA) and myeloperoxidase (MPO) activities. RESULTS: The pups in the NEC + CAPE group had better histopathologic and apoptosis evaluations (TUNEL and caspase-9) and the severity of bowel damage was significantly lower in the NEC + CAPE group compared to the NEC group (P < 0.01). The clinical sickness scores and body weight in the NEC + CAPE group was significantly better compared to the NEC group (P < 0.05). Tissue MDA, MPO, XO levels and TOS were remarkably reduced in the NEC + CAPE group, however, TAS was significantly increased in the NEC + CAPE group (P < 0.05). CONCLUSION: Treatment with CAPE reduces the intestinal damage in NEC.

Overhead is superior to underneath light-emitting diode phototherapy in the treatment of neonatal jaundice: a comparative study.

AIM: To compare the efficacy of overhead and underneath light-emitting diode (LED) devices in the treatment of neonatal jaundice. METHODS: We compared two LED phototherapy devices: the neoBLUE device, which provides overhead illumination, and the neoBLUE cozy device, which provides illumination from underneath the infant. The models we used had similar LED sources and provided similar light intensities (30 microW/cm(2)/nm). Infants with hyperbilirubinemia were assigned to one of two groups according to the phototherapy device used (group 1, overhead illumination, 181 infants; group 2, underneath illumination, 61 infants). Recorded variables included birthweight, gender, family history, aetiology of jaundice, total duration of phototherapy and total serum bilirubin (TSB) concentration at the initiation of phototherapy, at 12-hour intervals and just before the cessation of phototherapy. The rates of decrease in TSB concentration were calculated. RESULTS: There were significant differences in the mean duration of phototherapy and in the rate of decrease in TSB concentration between the two groups. The mean duration of phototherapy in group 2 was higher than in group 1 (P= 0.037). The rate of decrease in TSB in group 1 was higher than in group 2 (P= 0.01). CONCLUSION: These results suggest that when phototherapy is used in the treatment of neonatal jaundice, the direction from which the light is applied should be considered in addition to light source intensity.

Phototherapy increases DNA damage in lymphocytes of hyperbilirubinemic neonates.

Phototherapy is commonly used in the treatment of hyperbilirubinemia in newborns. No serious side effects related to phototherapy have been observed, but concerns regarding its potential to damage DNA have been expressed, based on animal or cell-culture studies. The aim of this study was to investigate, in neonates with hyperbilirubinemia, the possible relation between phototherapy and DNA damage. The study included 33 full-term newborns with non-physiological jaundice and 14 healthy newborns with physiological jaundice as controls. Phototherapy was performed with an array of six fluorescent lamps producing radiation with wavelengths of 480-520 nm at 12 microW/cm(2)/nm. DNA damage in lymphocytes was determined by use of the alkaline comet assay. The DNA damage increased significantly with the duration of phototherapy, as shown by measurements at 24, 48, and 72 h (P<0.001). These findings indicate that phototherapy, widely used in neonatology units, increases DNA damage in newborns. It remains to be seen whether the genotoxic effect observed in the present study can cause any long-term health effect in phototherapy-treated infants in later life.

Comparison between the use of saline and seawater for nasal obstruction in children under 2 years of age with acute upper respiratory infection.

BACKGROUND/AIM: The effectiveness of isotonic and hypertonic saline solutions used to open the nasal passage and improve clinical symptoms was compared in children under 2 years of age admitted with the common cold. MATERIALS AND METHODS: The study was performed as a randomized, prospective, and double-blind study. The study included 109 children. The children using saline (0.9%) and seawater (2.3%) as nasal drops (the patient group) and the control group (in which nasal drops were not administered) were compared. Seventy-four patients received nasal drops from package A (seawater) in single days and from package B (physiological saline) in double days. RESULTS: The mean age of the patients was 9.0 ± 3.9 months and the numbers of boys and girls were 65 (59.6%) and 44 (40.4%), respectively. There was no significant difference between Groups A and B in terms of nasal congestion (P > 0.05). However, a significant difference was found between the control group and Groups A and B (P < 0.05). CONCLUSION: Relief was seen in nasal congestion, weakness, sleep quality, and nutrition with the use of both saline and seawater in children with the common cold. Seawater or saline drops may be added to standard treatment protocols.

An abrupt increment in the respiratory rate is a sign of neonatal pneumothorax.

OBJECTIVE: The objective of the present study was to investigate the early clinical signs of neonatal pneumothorax. METHODS: A case-control study at a level III referral center from 2006 to 2012 was conducted. For each neonate with pneumothorax (Group I), one control subject (Group II) was identified by selecting an infant born within the same week with a gestational age of ± 7 days and with a birth weight within 10% of the index case. The primary outcome was to investigate the clinical findings preceding the onset of pneumothorax. Secondary outcome was to assess the risk factors. RESULTS: Of the 1375 infants admitted, 39 had a pneumothorax. Patients with pneumothorax showed significantly increased respiratory rates preceding the definitive diagnosis when compared with control patients (median: 16 (0-58) versus 4 (0-10); p < 0.001). An increase in the respiratory rate was found to be a significant clinical parameter preceding the diagnosis of pneumothorax (odds ratio (OR): 1.47, 95% confidence interval (CI): 1.12-2.14, p < 0.001; R(2) = 0.80). Sensitivity and specificity of this sign were found to be 77 and 90%, respectively. CONCLUSION: An abrupt increase in the respiratory rate would be used as a reliable parameter to help determine an impending pneumothorax in neonates.

Treatment of typhoid fever in children with a flexible-duration of ceftriaxone, compared with 14-day treatment with chloramphenicol.

Although the efficacy of ceftriaxone in typhoid fever is well documented, the precise duration of ceftriaxone therapy in children with typhoid fever is not established and varies from 3 to 14 days in the literature. In a prospective, randomized study ceftriaxone was compared with chloramphenicol for treatment of 72 children who had bacteriologically confirmed typhoid fever. Ceftriaxone was given at a dose of 75 mg/kg per day (maximally 2 g/day) intravenously, in two doses until defervescence and continued 5 days after that time. Chloramphenicol was given at a dose of 75 mg/kg per day (maximally 2 g/day) in four doses for 14 days. Mean defervescence time was in 5.4 days in the ceftriaxone group and 4.2 days in the chloramphenicol group (P=0.04). Clinical cure without complications was achieved in all patients in both groups. No patient relapsed in the ceftriaxone group, and four patients relapsed in the chloramphenicol group (P=0.048). The overall results of this study suggest that a flexible-duration of ceftriaxone therapy given until defervescence time, followed by an additional 5 days of therapy is a reasonable alternative to conventional 14-day chloramphenicol treatment in children with typhoid fever.

A descriptive study of transient neonatal feeding intolerance in a tertiary care center in Turkey.

OBJECTIVE: To investigate the characteristic features of transient neonatal feeding intolerance (TNFI) during the hospitalization for birth in the maternity ward. DESIGN: A prospective follow-up study. SETTING: Maternity ward and neonatal intensive care unit (NICU) in an academic medical center. PARTICIPANTS: Term (≥ 37-weeks gestation) infants admitted to the neonatal intensive care unit with recurrent vomiting and refusal to feed between January and December 2011. These infants were prospectively followed-up at 1, 2, 4, 6 months of age in the outpatient clinic. RESULTS: During the study period 1280 infants were evaluated in the maternity ward. Forty-eight (3.75%) neonates with repeated vomiting and refusal to feed were hospitalized from the maternity unit to the NICU Level I on the first postnatal day for further investigation. All infants started vomiting in the first day (median 5.75 hours; interquartile range: 1-24) and recovered by the 48(th) postnatal hour (median 27.5 hours; interquartile range: 14-48 hours). Laboratory and imaging studies showed no abnormalities. After discharge, 6-month follow-up of these infants showed no vomiting or feeding intolerance during well-child visits. CONCLUSIONS: Infants with TNFI can be managed with close observation and supportive measures if they have no other indications of underlying disease. We believe that expectant management and supportive measures under skilled nursing care will prevent unnecessary diagnostic evaluation, mother/infant separation, and prolonged hospital stay.
